The nvme_dma function doesn't just do DMA (QEMUSGList-based) memory transfers;
it also handles QEMUIOVector copies.
Introduce the NvmeTxDirection enum and rename to nvme_tx. Remove mapping
of PRPs/SGLs from nvme_tx and instead assert that they have been mapped
previously. This allows more fine-grained use in subsequent patches.
Add new (better named) helpers, nvme_{c2h,h2c}, that does both PRP/SGL
mapping and transfer.

assert may be compiled to a noop and we could end up returning an
uninitialized status.
Fix this by always returning Internal Device Error as a fallback.
Note that, as pointed out by Philippe, per commit 262a69f4282 ("osdep.h:
Prohibit disabling assert() in supported builds") this shouldn't be
possible. But clean it up so we don't worry about it again.

ZASL (Zone Append Size Limit) is defined exactly like MDTS (Maximum Data
Transfer Size), that is, it is a value in units of the minimum memory
page size (CAP.MPSMIN) and is reported as a power of two.
The 'mdts' nvme device parameter is specified as in the spec, but the
'zoned.append_size_limit' parameter is specified in bytes. This is
suboptimal for a number of reasons:
1. It is just plain confusing wrt. the definition of mdts.
2. There is a lot of complexity involved in validating the value; it
must be a power of two, it should be larger than 4k, if it is zero
we set it internally to mdts, but still report it as zero.
3. While "hw/block/nvme: improve invalid zasl value reporting"
slightly improved the handling of the parameter, the validation is
still wrong; it does not depend on CC.MPS, it depends on
CAP.MPSMIN. And we are not even checking that it is actually less
than or equal to MDTS, which is kinda the *one* condition it must
satisfy.
Fix this by defining zasl exactly like mdts and checking the one thing
that it must satisfy (that it is less than or equal to mdts). Also,
change the default value from 128KiB to 0 (aka, whatever mdts is).

Commit 6eb7a071292a ("hw/block/nvme: change controller pci id") changed
the controller to use a Red Hat assigned PCI Device and Vendor ID, but
did not change the IEEE OUI away from the Intel IEEE OUI.
Fix that and use the locally assigned QEMU IEEE OUI instead if the
`use-intel-id` parameter is not explicitly set. Also reverse the Intel
IEEE OUI bytes.

The Zone Append Size Limit (ZASL) must be at least 4096 bytes, so
improve the user experience by adding an early parameter check in
nvme_check_constraints.
When ZASL is still too small due to the host configuring the device for
an even larger page size, convert the trace point in nvme_start_ctrl to
an NVME_GUEST_ERR such that this is logged by QEMU instead of only
traced.

Firstly, if zoned.max_active is non-zero, zoned.max_open must be less

Secondly, if only zones.max_active is set, we have to explicitly set
zones.max_open or we end up with an invalid MAR/MOR configuration. This
is an artifact of the parameters not being zeroes-based like in the
spec.

The implementation uses a bounce buffer to first read in the source
logical blocks, then issue a write of that bounce buffer. The default
maximum number of source logical blocks is 128, translating to 512 KiB
for 4k logical blocks which aligns with the default value of MDTS.

nvme-ns device is registered to a nvme controller device during the
initialization in nvme_register_namespace() in case that 'bus' property
is given which means it's mapped to a single controller.
This patch introduced a new property 'subsys' just like the controller
device instance did to map a namespace to a NVMe subsystem.
If 'subsys' property is given to the nvme-ns device, it will belong to
the specified subsystem and will be attached to all controllers in that
subsystem by enabling shared namespace capability in NMIC(Namespace
Multi-path I/O and Namespace Capabilities) in Identify Namespace.
Usage:
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
-device nvme,serial=bar,id=nvme1,subsys=subsys0
-device nvme,serial=baz,id=nvme2,subsys=subsys0
-device nvme-ns,id=ns1,drive=<drv>,nsid=1,subsys=subsys0 # Shared
-device nvme-ns,id=ns2,drive=<drv>,nsid=2,bus=nvme2 # Non-shared
In the above example, 'ns1' will be shared to 'nvme0' and 'nvme1' in
the same subsystem. On the other hand, 'ns2' will be attached to the
'nvme2' only as a private namespace in that subsystem.
All the namespace with 'subsys' parameter will attach all controllers in
the subsystem to the namespace by default.

We have nvme-subsys and nvme devices mapped together. To support
multi-controller scheme to this setup, controller identifier(id) has to
be managed. Earlier, cntlid(controller id) used to be always 0 because
we didn't have any subsystem scheme that controller id matters.
This patch introduced 'cntlid' attribute to the nvme controller
instance(NvmeCtrl) and make it allocated by the nvme-subsys device
mapped to the controller. If nvme-subsys is not given to the
controller, then it will always be 0 as it was.
Added 'ctrls' array in the nvme-subsys instance to manage attached
controllers to the subsystem with a limit(32). This patch didn't take
list for the controllers to make it seamless with nvme-ns device.

nvme controller(nvme) can be mapped to a NVMe subsystem(nvme-subsys).
This patch maps a controller to a subsystem by adding a parameter
'subsys' to the nvme device.
To map a controller to a subsystem, we need to put nvme-subsys first and
then maps the subsystem to the controller:
-device nvme-subsys,id=subsys0
-device nvme,serial=foo,id=nvme0,subsys=subsys0
If 'subsys' property is not given to the nvme controller, then subsystem
NQN will be created with serial (e.g., 'foo' in above example),
Otherwise, it will be based on subsys id (e.g., 'subsys0' in above
example).

The read_tcnt() function calculates the TCNT register values for the
two channels of the timer module; it sets these up in the local
tcnt[] array, and eventually returns either one or both of them,
depending on whether the access is 8 or 16 bits. However, not all of
the code paths through this function set both elements of this array:
if the guest has programmed the TCCR.CSS register fields to values
which are either documented as not to be used or which QEMU does not
implement, then the function will return uninitialized data. (This
was spotted by Coverity.)
Add the missing CSS cases to this code, so that we return a
consistent value instead of uninitialized data, and so the code
structure indicates what's happening.

Now that the Xilinx CSU DMA model is implemented, the existing
DMA related dead codes in the ZynqMP QSPI are useless and should
be removed. The maximum register number is also updated to only
include the QSPI registers.

ZynqMP QSPI supports SPI transfer using DMA mode, but currently this
is unimplemented. When QSPI is programmed to use DMA mode, QEMU will
crash. This is observed when testing VxWorks 7.
This adds a Xilinx CSU DMA model and the implementation is based on
https://github.com/Xilinx/qemu/blob/master/hw/dma/csu_stream_dma.c.
The DST part of the model is verified along with ZynqMP GQSPI model.

The AN547 runs the APB peripherals outside the SSE-300 on a different
and slightly slower clock than it runs the SSE-300 with. Support
making the APB peripheral clock frequency board-specific. (For our
implementation only the UARTs actually take a clock.)

For the AN547 image, the FPGAIO block has an extra DBGCTRL register,
which is used to control the SPNIDEN, SPIDEN, NPIDEN and DBGEN inputs
to the CPU. These signals control when the CPU permits use of the
external debug interface. Our CPU models don't implement the
external debug interface, so we model the register as
reads-as-written.
Implement the register, with a property defining whether it is
present, and allow mps2-tz boards to specify that it is present.

Now we have sufficiently parameterised the code, we can add SSE-300
support by adding a new entry to the armsse_variants[] array.
Note that the main watchdog (unlike the s32k watchdog) in the SSE-300
is a different device from the CMSDK watchdog; we don't have a model
of it so we leave it as a TYPE_UNIMPLEMENTED_DEVICE stub.

Support SSE variants like the SSE-300 with an ARMSSE_CPU_PWRCTRL register
block. Because this block is per-CPU and does not clash with any of the
SSE-200 devices, we handle it with a has_cpu_pwrctrl flag like the
existing has_cachectrl, has_cpusectrl and has_cpuid, rather than
trying to add per-CPU-device support to the devinfo array handling code.

The SSE-300 has a system counter device; add support for SSE
variants having this device.
As with the existing devices like the cache control block, CPUID
block, etc, we don't try to make the MMIO addresses configurable. We
can do that if and when we need to model a future SSE variant which
has the counter in a different location.
